TOOL-HOLDER.

Patented July 30, 1907.

Application filed November 3, 1906. Serial 341,913.

had therein to the accompanying drawings.

This invention relates to tool holders of the character commonly employed in connection with lathes and similar machines, and the object of the invention is to provide a tool holder in which the tool may be secured at various angles relatively to the work without altering the position of the holder and to provide a simple meansfor so adjusting the tool and clamping the same in position.

With these objects in view the invention consists in the construction hereinafter to be described, and then more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan view of my device; Fig. 2 is a side elevation of the same; Fig. 3 is a perspective of the same, with the clamping member removed; and Fig. 4 is an inverted detail view of the clamping member.

In these drawings, the tool holder as a whole is indicated by the reference numeral 1 and is provided with a shank member 2 of the ordinary type which has at its forward end a tool holding head 3, which is preferably substantially triangular in shape and is provided on two of its sides near the lower edge thereof with grooves or guideways 4 having the inner edge thereof straight, as shown at 5, and the outer edge 6 inwardly beveled. The upper face of the triangular head 3 is provided with two grooves 7, one extending parallel with each of the grooves 4 formed along the side of said head. These grooves have their outer edges 8 vertical and their inner sides 9 beveled. The triangular head 3 is further provided with three screw-threaded apertures 10, 11 and 12, which are located adjacent to the three angles of said head. A clamping member 13, which is adapted to cooperate with said head for securing the tool in position, comprises an upper plate 14, provided with apertures 15 and 16 near the opposite ends thereof, and having downwardly extending side members 17 and 18, the side member 17 being of a length slightly greater than the distance between the lower portion of the groove 4 and the top portion of the head 3 and having its lower edge inwardly beveled to correspond with the bevel 6 of the groove 4. The side member 18 of the head 3 is of less length than the member 17 and is adapted to engage the groove 7 in the upper portion of the head 3 which extends parallel with the groove 4 engaged by the side member 17. The lower edge of the side member 18 is beveled to correspond with the beveled edge 9 of the groove 7.

To adjust a tool in the head, the same is placed in either groove 4 and the clamping member 13 placed in position thereon with the apertures 15 and 16 in engagement with either the threaded apertures 10 and 12 or 10 and 11 of the head 3 and is secured in position thereon by means of set screws 19 extending through the apertures'lG and 15, engaging the threaded apertures 10 and 11 or 10 and 12. The engagement of the beveled edges of the side members 17 and 18 with the beveled edges of the grooves 4 and 7 causes this clamping member to press firmly against the tool as the set screws 19 are tightened down to clamp the same rigidly in position. When it is desired to change the position of the tool, the set screws 19 are removed, allowing the removal of the clamping member 13 and the tool. The tool is then placed in the desired position in the groove 4 and the clamping member placed in engagement with the same as before, the clamping member in this instance occupying a reverse position to that which it occupied in the former arrangement, the apertures 16 and 15 registering with. the apertures 10 and 11, respectively, in the present instance, while in the former arrangement, the aperture 15 registered with the aperture 10 and the aperture 16 with the aperture 12, this reversal of position being made possible by the similar construction of the opposite ends of the clamping member 13.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent,

1. In a device of the character described, the combination, with a tool head having two pairs of guideways, the guideways of each pair being parallel, of a clamping member adapted to engage either pair of said guideways and clamp the tool in position, substantially as described.

2. In a device of the character described, the combination, with a triangular tool head having tool grooves formed along two sides thereof, and grooves formed in the upper face thereof, one of the grooves in the upper face of said head extending parallel with the tool groove on one side thereof, and the other groove on the upper face of the head extending parallel with the tool groove on the other side thereof, of a clamping member adapted to engage either pair of said parallel grooves and to clamp the tool in position in said head, substantially as described 3. In a device of the character described, the combinatien, with a triangular head, guideways formed along two sides of said head and having their outer faces beveled, grooves in the upper face of said head having their inner faces beveled, of a clamping member and downwardly extending portions carried thereby adapted to engage said 10 grooves and having their lower edges beveled to engage the beveled faces of said grooves, and means for securing said clamping member in position on said head, substantially as described.

In testimony whereof, I aflix my signature in presence of two witnesses.
